Abstract

A cyclone separation device includes a cyclone chamber and an airflow guiding member. The cyclone chamber includes an air inlet, an annular sidewall forming an air receiving region therein communicating with the air inlet and guiding an airflow to flow spirally in the air receiving region, and a dust collecting region and an air outlet disposed at two ends of the cyclone chamber along an axis of the cyclone chamber. The dust collecting region communicates with the air receiving region. The airflow guiding member is disposed at the dust collecting region, and includes an airflow guiding chamber, at least one airflow entry opening communicating with the dust collecting region and airflow guiding chamber, and an airflow discharge opening communicating with the airflow guiding chamber and disposed on the axis of the cyclone chamber to face the air outlet and output the airflow to form an air discharging region.

Claims

1. A cyclone separation device of a cyclone vacuum cleaner, comprising:

a cyclone chamber, comprising;

an air inlet, allowing an airflow to enter the cyclone chamber;

an annular sidewall, forming an air receiving region therein communicating with the air inlet, and guiding the airflow to flow spirally in the air receiving region; and

a dust collecting region and an air outlet, disposed at two ends of the cyclone chamber along an axis of the cyclone chamber, wherein the dust collecting region communicates with the air receiving region, and wherein the air outlet discharges the airflow; and

an airflow guiding member, disposed at the dust collecting region, comprising;

an airflow guiding chamber;

at least one airflow entry opening, communicating with the dust collecting region and the airflow guiding chamber, and allowing the airflow in the dust collecting region to enter the airflow guiding chamber; and

an airflow discharge opening, communicating with the airflow guiding chamber, disposed on the axis of the cyclone chamber to face the air outlet and output the airflow from the airflow guiding chamber to form an air discharging region.

2. The cyclone separation device of claim 1, wherein the airflow guiding member comprises an airflow rebounding surface that encircles the airflow discharge opening and faces the air outlet.

3. The cyclone separation device of claim 2, wherein the airflow rebounding surface is an arched surface and is recessed toward the dust collecting region.

4. The cyclone separation device of claim 2, wherein the airflow guiding member comprises a choke slanting surface extended from the airflow rebounding surface toward the air receiving region.

5. The cyclone separation device of claim 1, wherein the airflow guiding member comprises a dust limiting surface facing the dust collecting region.

6. The cyclone separation device of claim 1, wherein the airflow guiding member comprises a support section connected to the cyclone chamber, and a connecting section connected to the support section and extended toward the air outlet;

the airflow entry opening is disposed at the connecting section.

7. The cyclone separation device of claim 1, wherein the air outlet and the airflow discharge opening of the airflow guiding member are disposed coaxially.

8. The cyclone separation device of claim 1, wherein the cyclone chamber comprises a dust outlet communicating with the dust collecting region.

9. The cyclone separation device of claim 1, wherein the cyclone chamber comprises an air discharging duct forming the air outlet and extending toward the dust collecting region, the air discharging duct has a length exceeding the position of the air inlet.

10. A cyclone vacuum cleaner, comprising:

a cyclone separation device, comprising;

a cyclone chamber, comprising;

an air inlet, allowing an airflow to enter the cyclone chamber;

an annular sidewall, forming an air receiving region therein communicating with the air inlet, and guiding the airflow to flow spirally in the air receiving region; and
